  3. Detectors Examples Using Panoramix for Geometry Visualization • The new geometry element is part of a DB slice . • Let us call this local Db slice : ‘myDDDB-Tutorial-LHCb-Feb2012’ • Step1: Create a file ‘DetDb_Tutorial.py’ which has something like: from Configurables import LHCbApp, CondDB, UpdateManagerSvc,DDDBConffrom Gaudi.Configuration import *lhcbApp = LHCbApp()DDDBConf().DbRoot = "/afs/cern.ch/user/s/seaso/scratch0/cmtuser/SQLDDDB/db/myDDDB-Tutorial-LHCb-Feb2012/lhcb.xml"CondDB().Tags['DDDB'] = 'HEAD'lhcbApp.DDDBtag = "head-20110914"lhcbApp.DataType = "2010"lhcbApp.Simulation = TrueLHCbApp().CondDBtag = "sim-20111020-vc-md100” • Step2: SetupProjectPanoramix v20r2 python $mypanoramix --BareConfig 1 –f none -v DetDb_Tutorial.py

  4. Detectors Examples Using Panoramix for Geometry Visualization • Step 3: In the Panoramix window, click through the geometry tree dd Structure Geometry AfterMagnetRegion TutorialMaster lvTutorialMaster • Step 4: Use the info from HelpGeometry to navigate into the volumes • Demonstration from an lxplus window. • Simple Solids, Boolean subtracted Solid. • Array of solids

  5. Detectors Examples Panoramix Demonstrations • More info related to • running Panoramix • and copying the XmlVis • in backup slides

  6. Detectors Examples More Examples • Example Volumes : Three PixelContainersinside TutorialMaster • Arrays of pixels inside each PixelContainer Demonstration using Panoramics

  7. Detectors Examples Exercises Create a boolean subtracted Box , starting from the Tutorial example and visualize it in Panoramix. It can be a box with two cylindrical holes. Example shown here. Use the instructions in earlier slides To get the DB, before making modifications. The instructions for Running panoramix are also in earlier slides. An example solution is also provided in the database.

  8. Detectors Examples Exercises In the example with Pixelcontainer, create pixels in a way which is symmetric around the beam axis. An example is shown here with pixels in the shape of r-phi geometry.

  9. Use the volume create in Exercise 2 to run Gauss with particle gun and print (a) The location of where the tracks are incident on the PixelContainer. (b) The location of where the tracks are incident on the pixels. Use the instructions from backup slides to run Gauss. Detectors Examples Exercise2: Part2After the Geant4 lecture

  10. Detectors Examples BACKUP SLIDES

  11. Detectors Examples DB Slice for Tutorial : Instructions for Panoramix • For the Tutorial, a DB slice is made where the RICH2 is temporarily kept aside. • The space for that is used to create a TutorialMaster Volume within which • we can create additional volumes in this tutorial. • This can be copied to your area using instructions on page 2 • Visualization attributes to volumes (colours , wire frames etc). • The Tutorial Volume attributes in TutorialLogVols.xml, TutorialVisAtts.xml and • colors.xml setenvProjectPanoramix v20r2 cd ~/cmtuser/Panoramix_v20r2 getpack Vis/XmlVis head Optional: getpack Vis/Panoramix v20r2 run $mypanamix from the options area of this panoramix.

  12. Detectors Examples Example running of Gauss • setenvGauss v41r1 • cd ~/cmtuser/Gauss_v41r1 • getpackSim/Gauss v41r1 • getpack Gen/LbPGuns • getpack Tutorial/GaussTutorial head • Compile the GaussTutorial • Edit Gauss requirements to use this packge • Copy the options files in • /afs/cern.ch/user/s/seaso/public/Simulation/Tutorial/TutorialOptions • Use the standard Particle Gun options • (alternately copy the options file ParticleGun_rich2.py from • /afs/cern.ch/user/s/seaso/public/Simulation/Tutorial/Gen/LbPGubs/options area.) • gaudirun.py Gauss-DB-Feb2012-Tutorial.py • Gauss_Job_TutorialUserPackage.py

  13. Detectors Examples Exercise solutions 1: In the ../myDDDB-Tutorial-LHCb-Feb-2012/TutorialExample cp geometry_exercise1.xml geometry.xml cp structre_basic.xml structure.xml SetupProjectPanoramix v20r2 python $mypanoramix --BareConfig 1 –f none -v DetDb_Tutorial.py 2: In the ../myDDDB-Tutorial-LHCb-Feb2012/TutorialExample cp geometry_exercise2.xml geometry.xml Then run panoramix as above To run gauss use the instructions on the previous slide

  14. Options for using volumes inside TutorialMaster geometry_setA.xml : basic geometry geometry_SetP.xml : few boolean solids geometry_SetCoinA.xml : array of coins geometry_SetPix.xml : PixelContainer geometry_Exercise1.xml, geometry_Exercise2.xml, geometry_Exercise3.xml : solutions to the exercises cp geometry_xxx.xml geometry.xml for the using the various setups structure_basic.xml : basic geometry, boolean solids , PixelContainer etc. With PixelContainer geometry: structure_GenericDetElem.xml : generic detector element structure_MasterSpDetElem.xml : customized detector element. structure_exercise3.xml : solution to exercise 3 cp structure_xxx.xml structure.xml to use the various options.
